Kungani obomvu inyanga phakathi kwelanga zabo noma kwelanga?

Uma owake ukubukela ukuphuma kwelanga noma kwelanga ebusuku izibani ngokuqinisekile okwamanje ukunakwa kwakho bakhangwa nombala engavamile kanye nosayizi. Kungani inyanga sibomvu njengomlilo, kodwa ezinkulu, uma iseduze esele uzokuzaliseka? Uma usayizi namanje ngandlela-thile Kungenzeka ukuba achaze kuwutalagu elihlobene ne the kwalungiswa izinkunga zokubona yokukhanya, manje-ke kuthiwani luhlaza elikhanyayo orange? Ezinsukwini ubudala, lapho abantu zazingakabi sesimweni nokubhala ngakho, ukuze uqonde ukuthi kungani inyanga elibomvu ngezikhathi ezithile, umbala engavamile ithathwa njengendlela sokuhle iyinkathazo zehlakalo ezimbi. Futhi kuthiwani yethu ososayensi isikhathi ukuchaza lesi simo?

umbala yokuguqukela kwesinye isimo

Uma ubheka Earth satellite kusuka isikhala (nzima emcabangweni wakho akadingi - the osomkhathi kwase kuyisikhathi eside kusukela wenza isibhamu sakhe), khona-ke izovela thina ukukhanya grey ibhola kahle engenisa ukukhanya kwelanga. Osomkhathi kungukuthi ukunwaya amakhanda abo phezu kungani inyanga osasitini nezinguquko umbala satellite kuphela uma ubuka it kusuka komhlaba. Lapho ukukhanya ebusuku iyaqala nje avuke lé, kubukeka sengathi umbuthano omkhulu orange. Iplanethi yethu lumayelana axis awo. Inyanga kunqoba kwembulunga, futhi umbala izinguquko zalo. Ekuqaleni luhlaza orange iba phuzi, futhi ngemva kwesikhathi esithile - okumhlophe futhi ephuzi. Lapho inyanga ithatha izintambo, isikhundla sokuba inhloko ye obukele, kwakungase cishe iba grey ukukhanya. Yiqiniso, empeleni, umbala waso ayishintshi satellite eMhlabeni. Lonke imfihlo ukuthi sibheka-ke shining kudlule emkhathini, futhi kufana nje ebuka into edabula isihenqo.

Kungani inyanga osasitini ekuseni?

Ngaphambi ukukhanya kubonakala kusukela satellite ukufinyelela amehlo ethu, kwakufanele bonyana enze zidlule emoyeni, ehlanganisa i-nitrogen, umoya-mpilo namanye amagesi. Wona, kanye nawo izinhlayiya ezincane kunazo ngothuli, intuthu kanye nezinye ezingcolisayo nakanjani zishintsha Spectral yokukhanya, kubonakale olisunduza liye ngase ebomvu. Yingakho nenyanga elibomvu ngesikhathi ekuqaleni kosuku. Lo mphumela ephawuleka ikakhulukazi ezinomoya, isimo sezulu ezicindezelayo noma ngesikhathi imililo uma izinhlayiya ezincane entrained inhlabathi phezulu futhi, ngaphandle kokuba ukuze kuxazululwe amahora hang emkhathini. Kunenye ngencazelo yokuthi kungani inyanga ibovu. Siqukethe e ukuthi shortwave spectrum welanga lapho imisebe ayahlakazeka yi Earth, kanye nombono eside idlule umkhathi kubonakala kusukela umhlaba satellite. Kuyinto ba abanikeza ebusuku inkanyiso abomvu.

Kungani inyanga ngezinye izikhathi kubonakala omkhulu?

Ezinye izithombe ungabona ukuthi satellite Zomhlaba, ngokuba lalingabonakali emkhathizwe, ubukeka improbably ezinkulu. Ngezinye izikhathi lesi simanga kungabonwa, futhi yena, futhi ngakho ukusho ukuthi ubukhulu of the Moon is overestimated kuletitfombe akunikezi inani langempela, akudingekile. Incazelo yaleli Empeleni kukhona eziningana. Okokuqala, lokhu kuwutalagu ixhunyiwe nge isici esithakazelisayo ehlweni lomuntu - ngemisebe: egqamile ukukhanya izibalo on isizinda emnyama kubonakale njalo ukuba abangaphezu kuka-usayizi zabo zangempela. Okwesibili, ngokuvumelana theory ohlongozwayo-yalolucwaningo 60. James Rock uLloyd Kaufman, ubuchopho bethu ngandlela-thile "ukholelwa" ukuthi uhlobo Dome yasezulwini ayilungile, kungathi isicaba Nenkabazwe. Ngenxa yalesi sizathu, izinto emkhathizwe Ubonakala kunangendlela leyo ngesikhathi zenith. Futhi naphezu kweqiniso lokuthi iso uyaphawula usayizi njalo emincane of the Moon (mayelana 0.5 degrees), ubuchopho ilungisa ngokuzenzakalelayo ibanga, futhi siye sithuthukiswe isithombe into waphawula. Nokho, ososayensi baye okwamanje isinqumo okuyinto kwemfundiso yokuziphendukela ezihlongozwayo iyona ozwakalayo kakhulu.
